Two Kids Found This Creepy Secret In Their House

#10
A Normal Room

Would you suspect this room of being anything but normal if you just moved in? It looks like a den or office with a bookcase full of books. Knowing what we know now, it makes you realize how looks can be deceiving, and that you think you are seeing is not really the reality of what it is. How long would it have taken for the boys parents to figure out that the secret door existed, and would the people have continued living in there until then? This seems to be a mystery that will never be solved.
